Mitigating climate change by CO₂ air capture and geological storage: Opportunities for Iran

This paper investigates the preliminary strategies and tools for the implementation of CO₂ air capture and geological storage as a potential mitigation option in the future climate policy of Iran. It is a method to capture CO₂ directly from air and store it in geological structures based on large-scale industrial processes to enable the near-permanent sequestration of carbon. The reason for selecting this approach originates from its capability to mitigate CO₂ from all economic sectors with a single technology, while the conventional capture methods are designed only for mitigation of CO₂ from point sources of the power generation and industrial sectors. In order to facilitate the workflow of air capture as efficiently as possible, this study suggests some tools and directions for the selection of potential sectors and the prospective areas for the final site selection of the air capture units.
